10 Claims.

This invention relates to window channels such as are used for mountinga glass or sash in a vehicle, such, for example, as an automobile,aeroplane, motorboat, or the like. Under certain con-'- ditions, it isdesirable to provide what may be termed a deep channel having more depththan the ordinary conventional Window channel, so that the glass or sashmay have a substantial movement transversely of the channel Withoutactually leaving or pulling out of the channel. It is to such deepwindow channels that the present invention particularly relates,although many of the features of the invention are applicable also toother forms of channel.

One object of the invention is the provision of a generally improved andmore satisfactory deep window channel.

' Another object is the provision of improved means for holding one ormore cushioning elements in posit-ion on the Window channel.

Still another object is the provision of a deep Window channel having asheet metal body which is relatively small in comparison to the depth ofthe complete channel.

' A further object is the provision, in a Window channel, of improvedmeans for holding a cushioning element, and particularly of such meansin connection with an element which is substantially in the plane of aside wall of the channel and extends outwardly to form a continuation ofthe side wall.

To these and other ends the invention resides in certain improvementsand combinations of parts, all as will be hereinafter more fullydescribed, the novel features being pointed out in the claims at the endof the specification.

In the drawing:

Fig. 1 is a side elevation of a window channel constructed in accordancewith one embodiment of the invention;

Fig. 7 is a transverse section substantially on the line of Figs. 5 and6, and

Fig. 8 is a view similar to a fragment of Fig. '7, on a larger scale, toillustrate details.

The same reference numerals throughout Vthe several views indicate thesame parts.

Referring now to the embodiment of the in- 5 vention illustrated inFigs. 1 to 4 inclusive, there is shown what might be termed a deepchannel member having side walls |0 and aback and bottom wall l, allformed preferably from a single piece of suitable material, such assheet metal. 10 This channel-shaped 'member may be wider and deeper thanthe usual window channel, so that a channel I2 of th-e usual size may beembraced within the deep channel member and secured thereto by anysuitable means such as the rivets 3. `'I'his channel member `|2 may beof any suitable known construction, such for example as that shown inSchlegel Patent No. 1,847,700, issued March 1, 1932, orthat shown inSchlegel Patent No. 1,895,688, issued January 31, 1933, or 20 that shownin Schlegel Patent No. 1,928,574, issued September 26, 1933, to mentiononly a few o-f the kpossible constructions already known to thoseskilled in the art. In this inner channel I2 may be any suitablecushioning means indi- 25 cated diagrammatically at I5, such forexample, as the cushioning means shown in any of the above mentionedprior patents. Cushioning means in the form of relatively long stil'pile such as disclosed in the above mentioned Patent 30 No. 1,847,700,is frequently preferred and is here shown diagrammatically in thedrawing.

The two side walls I0 of the deep channel body preferably do not extendthrough the entire depth desired in the channel, but are terminated 35somewhat short of the intended extreme outer edge of the channel and areprovided with slits or slots 20 extending inwardly from the outer edgeto subdivide a portion of the outer edge into a plurality of tongues 2|and 22. Alternat- 40 ing tongues, such as those designated by thenumeral 2|, may be displaced laterally 'in one direction, with theintermediate tongues 22 displaced laterally in the opposite direction.'Ihen a cushioning element is placed between' the 45 tongues 2| and 22and held in place thereby.

The cushioning element comprises a woven body 25 which may be offlexible or semi-flexible material such as felt or a woven textilefabric of any suitable kind. Preferably it is a textile body 50 wovenfrom weft strands 26 and warp strands 21 indicated diagramamtically inFig. 4. Some or all of the weft strands 26 are preferably formed ofmetallic wire to stiften the body, while some or all of the warp strands21 may be woven 55 of any suitable non-metallic textile material, suchas cotton or linen.

The body 25, as shown, lies substantially in the plane of its associatedside wall l0 of the metallic channel, and forms, in effect, an outwardcontinuation or prolongation of the side wall. The inner edge of thecushioning element may have a binding strip 30 of suitable sheetmaterial, such as sheet metal, wrapped around the edge as shown, andthis bound edge is then clamped between the tongues 2| and 22, which areforced toward a common plane so as to clamp the edge of the cushioningelement firmly between them, as is plainly apparent from Fig. 3 of thedrawing.

The cushioning element body 25 may itself form 'the desired cushioningpads, or separate cushioning pads may be formed on one or both sidewalls of the body 25. Such cushioning pads may be in the form of therelatively long stiff pile disclosed in the above mentioned SchlegelPatent No. 1,847,700, or in the form of the cushioning pads disclosed inany of the other above mentioned Schlegel patents, or of relatively longuncut loops as disclosed in the copending application of Charles P.Schlegel, Serial No. 595,- 352, led February 26, 1932, for Windowchannels, or in any other form known to those skilled in the art.Preferably, however, relatively long stiff pile is used to form thecushioning pads, and this pile may be formed substantially as disclosedin the copending application of Charles P. Schlegel, Serial No. 660,402,iiled March 11, 1933, for Window channel. In this last mentionedapplication, long stilipile is applied to a woven base, woven in partfrom metallic wires, and this construction is especially suitable in thepresent instance The weft strands 26 shown in Fig. 4 of the presentdrawing may correspond, for example, to the strands 23 shown in Fig. 3of the drawing of the last mentioned Schlegel application, these strandspreferably being mostly or wholly of metal, while the non-metallic warpstrands 21 of the present application may correspond to the non-metallicstrands 2| the last mentioned Schlegel application. The cushioning padmay be formed, as in the Schlegel application, by relatively long sti'pile strands 3| (corresponding to the pile 30 or 3| of the Schlegelapplication) woven into the body or foundation strands as disclosed, forexample, in said Schlegel application, and held, for example, by weftstrands 32 corresponding to the strands 22 of the Schlegel application.These cushioning strands 3| may be formed on one or both sides of thebody 25. If only on one side, then they preferably extend inwardly fromthe inner side of the body 25 toward the mid plane of the channel, toprovide adequate cushioning support for a window glass indicated at 34.

One or both of the outer edges of the cushioning elements 25 may beprovided with a bead 3'1 formed of any suitable sheet material, such assheet metal, bent to a rounded cross section and embracing a portion ofthe outer edge of the cushioning element body 25 and runninglongitudinally along this edge, as shown. The edge of the cushioningelement may be somewhat enlarged, if desired, in order that the bead 3`|may grip it more firmly, such enlargement being secured, for example, bythe use of an enlarged warp strand 36 extending along the body 25approximately at its edge. These beads 31 not only assist in holding theedges of the somewhat iiexible cushioning elements straight and true,but also provided a decorative finish for the outer edges of the channelwhen these edges are used in a position in which they are exposed toview.

The channel |2 with its cushioning means |5 provides cushioning supportfor the edge of the window 34 when the window is moved toward the backor base of the channel, which may be to the fully closed position of thewindow, and which is shown in dotted lines in Fig. 2. The cushioningpads 3| also cushion the sides of the window when it is in thisposition, and furthermore provide cushioning support for the window whenit is moved slightly outwardly with respect to the channel, from thedotted line position to the full line position shown in Fig. 2 of thedrawing. Such a movement may be made to open part of the window forVentilating purposes or the like, as understood by those skilled in theart.

In Figs. 5 to 8, inclusive, of the drawing there is shown a modiedembodiment of the invention which is preferred under some conditions.Here, the various elements of the construction may be identical withthose of the construction shown in Figs. l to 4 except as hereafternoted, and corresponding elements are designated in Fig. 5 to 8 by thesame reference numerals used in Figs. 1 to 4, with the addition of theletter a, Thus the cushioning element in Figs. '7 and 8 is designted25a, while that in Fig. 2 is designated as 5.

The principal difference between the construction now being describedand the previous construction, is tha-t the slits which form the tongues2|.w and 22a., instead of being substantially parallel to each other tomake substantially rectangular tongues, are at an angle to each other tomake tongues which are not rectangular. The tongues 2| a are preferablyapproximately triangular, as shown, with relatively sharp points attheir outer ends, and these points are turned over as indicated at 23 toextend in a direction substantially at right angles to the plane of theassociated wall |00., so that when the tongues 2|a and 22a. are pressedtoward each other to clamp the cushioning element between them, thesharp points 23 (lying preferably just beyond the edgev of the bindingstrip 30a) press firmly intov and partly through the cushioning element25a and thus lock it securely in place. Also, the extreme outer edges ofthe other tongues 22a may extend to a point slightly beyond the edge ofthe binding strip 30a and may be bent down slightly over the edge! ofthe binding strip, as shown at 24 in Figs. 7 and 8, to assist in holdingthe cushioning elements securely.

With this construction, because of the secure interlock between thepoints 23 and the cushioning element, the Various tongues themselvesneed not be sosolid and rigid as in the preceding embodiment, andconsequently the sheet metal or other material from which the channelmember |0a is made may be considerably thinner than in the precedingcase. By comparing Figs. 2 and 4 of the drawing with Figs. 7 and 8, itwill be seen that the sheet metal Illa, in the latter figures isindicated as being materially thinner than sheet metal I0 in the formerfigures.

As previously stated, the cushioning pads may be formed on one or bothsides of the cushioning elements 25, and in Fig. 7 there are showncushioning pads 40 on the exterior surfaces of the cushioning elements25a as well as the cushioning pads 3|a. on the interior surfaces. 'Ihesecushioning pads 4D may be formed in any suitable known manner, asdisclosed, for example, in the patents and applications above mentioned,but preferably are formed from relatively long stiff pile in the mannerabove referred tol in connection with the pads 3|.

When the channel is placed in a groove or rabbet of the window frame ofthe vehicle to which it is applied, the pads 40 on the lexterior of thecushioning element provide cushioning between the channel and side wallsof the groove or rabbet, and thus prevent rattling or squeaking whichmight be caused by direct contact of the channel with the walls.Obviously such exterior cushioning maybe applied to the form of channelshown in Fig. 2 as well as to that shown in Fig. 7.

Elli/bile certain embodiments of the invention have been disclosed, itis to be understood that the inventive idea may be carried out in anumber of ways.
